Well, bio-hazard. Judging by what I've come across, I'm guessing this is a commission or something. None of the other stuff he's done (that I could find) has shit like lipples. Plenty of the other stuff, but I get the feeling someone payed for this thing.
No doubt. The dude has always been drawing weird things, starting with a lot of cock vore, but by the looks of it, he seems to have switched over to anal vore ending in scat. I swear, when you see the latter, you start to beg for him to go back to the other, because, at least comparatively, it's not fucking nauseating like poop shit is.
